4.1 Adjustments
TEST mode activation
Press the heating buttons (details 3 and 4 - fig. 1) together for 5 seconds to activate the
TEST mode. The boiler switches on irrespective of the system or DHW request.
The heating symbol (detail 24 - fig. 1) and DHW symbol (detail 12 - fig. 1) flash on the
display.
fig. 26 - TEST mode
To deactivate the Test mode, repeat the activation sequence.
The TEST mode is automatically disabled in any case after 15 minutes.
Burner adjustment
The burner is factory-set as given in table 4. It is possible to set the burner to a different
power output by means of pump pressure adjustment, nozzle, head and air adjustment
as described in the following sections. In any case, the new power setting must come
within the boiler's nominal working range. After making any adjustments, use a combus-
tion analyser to check that the CO % in the fumes is between 11% and 12%.

Oil nozzle delivery table
table 5 indicates the oil deliveries (in kg/h) as the pump and nozzle pressure changes.
N.B. - The values given in the table are approximate, since the nozzle deliveries can vary
by ± 5%. Also, for burners with a preheater, the fuel flow rate decreases by approximately
10%.

Pump pressure adjustment
The pump pressure is factory set for optimum operation and should not normally be
changed. However, if special needs require a different pressure, after applying the pres-
sure gauge and lighting the burner turn the adjustment screw "6" indicated in fig. 28. It is
anyhow recommended to keep within the range of 10 - 14 bar
